(9), MS receives that conference member increases after request, and confirms successfully to CS;

(10), CS sends UPDATE message to N side's conference member, change media successively;

(11), member side user receives after UPDATE message, change media, and reply 200, until all conference members join in meeting, finally complete the foundation of meeting.

Beneficial effect of the present invention is: within a predetermined period of time by sip terminal initiating conference flexibly, one key invites predefined conference member to participate in a conference, meet the flexibility that meeting is initiated, also improved meeting and initiated efficiency, solved group can initiator the problem of initiating conference voluntarily within a predetermined period of time.

Brief description of the drawings

Fig. 1 is the principle schematic of existing conference system;

Fig. 2 is schematic diagram of the present invention.

Embodiment

Further describe technical scheme of the present invention below in conjunction with embodiment, but described in claimed scope is not limited to.

As Fig. 1, at the appointed time interior initiation reservation meeting of conference system mostly, the conference member pre-setting is added in meeting, subscribes holding of meeting and need to be first subscribe through conferencing resource, then conference system in the time of specifying automatically by the incoming call meeting of all participant sides

As Fig. 2, a kind of soft switch implementation method of the predefine meeting of being initiated by sip user, suppose that in soft switch, predefine convention business access code is " * 60 ", and conferencing resource and predetermined in advance with conference member, within the conference reservation time period, the flow process of sip terminal initiating conference comprises following steps:

(1), group can initiator be that conference dispatching is presided in non-group can state time, press group can button enter group can state, dispatched users sends INVITE request message initiation session to call server CS simultaneously, called number user is conference member;

(2), CS receives INVITE request message, analyze the group meeting business for conference dispatching, trigger service logic: CS according to group meeting initiator's INVITE request message, search conference member, and initiate INVITE session request to all conference member users, called user terminal is received after request for conference, needs automatic-answering back device immediately, sends 200 responses to CS;

(3), CS receives after first called response, sends ACK to it, while sending out, 200 responses, to caller dispatch terminal, make both set up media channel simultaneously;

(4), group can initiator receiving after 200 responses, sends ACK to CS;

(5), CS receives that after second 200 called response, the tripartite that foundation need to be conversed form meeting, and to media server MS request, group can initiator be joined in meeting;

(6), MS receives that conference member increases after request, allocation of conference resources, and confirming successfully to CS;
